One woman told ABC11 she was sleeping on the streets and another man told 911 he was walking through an alley way when a group of teenagers assaulted them.
On Tuesday night, Ardena Best was sleeping on a park bench when she said out of nowhere a mob of young men approached her.
"I happen to look across the street, I see a whole group of guys...like 15 of them," Best said.
She said the men crossed Fayetteville Street, and one stopped and yelled at her before the attack.
"'What are you scared?' And the guy looked and punched me on the side of my face real fast," Best said. "He clutched his fist and slugged me above my eye."
She's not the only victim.
In a 911 call, a man told dispatch a group of teenagers running down Fayetteville Street said "excuse me sir" and punched him in the face.
Police said the two incidents sound similar. They describe the attackers as a group of African-American teens wearing gym clothes and traveling in a large group.
Best says until they are caught, she fears for her safety.
"I fear for my life now. That's where I sleep. I don't even have anywhere to sleep," she said.
